Soil contamination of organic origin is a major environmental challenge. One of the most common reactions in nature is the electron exchange between chemical species, also known as a reduction-oxidation (redox) reaction. Redox reactions drive organic matter degradation in the ground. Monitoring these reactions is therefore needed to protect soil and groundwater. This work aims to provide non-invasive monitoring methods to study redox state changes that occur in the near-surface interface, at the boundary between aerobic and anaerobic conditions, as well as a potential remediation solution to attenuate the negative impact of anaerobic condition.
